The Johnford SH CNC bridge mill series delivers unmatched performance and rigidity in a remarkably space-efficient design. With extended Y-axis travel of 1778 mm (70″), the SH series is engineered to handle demanding heavy machining applications while minimizing floor space requirements. Built with a massive single-piece Meehanite cast structure, these machines absorb cutting stresses with minimal deflection for exceptional accuracy — even in the most challenging cuts.
- Unique one-piece bridge and columns casting
- Full-length Meehanite cast iron base for 100% table support
- Hardened and ground box ways in both Y and Z axes for maximum rigidity
- 2-speed gearbox spindle drive for high torque cutting
- Hydraulic Z-axis counterbalance for smooth motion control
- Easy-access, high-speed automatic tool changer (ATC)
- 100% full enclosure to contain chips and coolant
- Complete chip removal system with two screw-type conveyors plus one belt conveyor
- Superior ergonomics with just 30.7″ table height from the floor
